* – under the index Z32SE.

Disadvantages of the Y32SE engine

  • Quite a lot of problems for engines of this series are caused by an unreliable crankcase ventilation system.
  • Another weak point of the motors of this series is the ever-leaking heat exchanger.
  • Closer to 250,000 km, the performance of the oil pump decreases, which is fraught with overturning.
  • Keep an eye on the cooling system; if it overheats, it will quickly blow through the cylinder head gaskets.
  • Ignition coils, lambda probes and crankshaft position sensor are also often replaced.
